【摘要】 基于虚拟现实的岸吊仿真系统的培训是当今及未来岸吊培训学习的重要方向之一。国内对于岸吊仿真系统的研发还处在起步阶段,有的虽在实验阶段已获得成功,但是系统集成性有待提高,民用推广方面尚有欠缺,有必要设计开发一种高效实用的多功能岸吊仿真系统。清华大学深圳研究生院现代物流中心物流与仿真实验室于2008年成功研制出一套岸吊仿真系统,该系统在软、硬件研发方面都取得较大突破。同年9月份我实验室在充分吸收该套系统科研成果的基础上,再次组织人员独立开发一套功能完整的、更具工业用途的岸吊仿真系统。本文正是围绕这一系统的设计研发展开。首先对仿真系统进行新的功能定位及总体设计,之后对前任成员研制的软件部分进行完善和修改,优化了系统结构及仿真模型,然后结合软件功能设计出配套的硬件方案,最终集成软、硬件,开发出我实验室第二套岸吊仿真系统。研究和设计开发的过程遵循了从整体到局部、并行化开发、由点到面的原则方法,并按照完善功能、优化仿真效果、调试修改、硬件支持软件的步骤,完成了岸吊仿真系统研究和设计开发。系统具有采用真实的岸吊操作台、单投影斜屏幕显示、多种环境模拟等特点。本文的主要内容包括:(1)提出了一种功能齐全的岸吊仿真系统设计方案。(2)分别设计了软件集成及软硬件的集成方法。(3)完善软件系统功能、优化仿真模型。(4)设计并比较了几种硬件设计方案。(5)指出系统的可扩展性及未来开发设计方向。其中,利用系统集成及Virtools开发平台进行仿真优化是本文的重点。优化仿真模型的技术关键主要在于振动仿真、空气阻尼等因素的影响和提高模型的真实性与实时性。本文将振动仿真问题转化为视景抖动来解决,分别分析空气阻力、天气状况及光线明暗等因素对模型的影响。更多还原

【Abstract】 The quay crane simulator training is an important orientation of quay crane training now and in future. The domestic study and design on quay crane simulator has just begun. Although some have been successful in the experimental stage, but the system integration needs to be improved, and there is a lack of civilian promotion.It is necessary to develop an efficient, practical and multifunctional quay crane simulator training system.Modern Logistics Center Logistics and Simulation Laboratory , Graduate School at Shenzhen, Tsinghua University, successfully developed a set of quay cranes simulation system in 2008, the system hardware and software have made great breakthroughs in research and development. In the same year in September I fully absorb the laboratory of the system based on scientific research, more re-organizations have developed a new quay cranes industrial use simulation system. This article is designed around the development of this new system started. First of all, the new simulation system location and design of new features, then some of the original system software changes to improve and optimize the system structure and the simulation model, and then combined with software features to design the hardware supporting the program, the final integration of software and hardware, I developed a second set of quay cranes laboratory simulation system. Research and design development process followed the bottom-up modeling , parallel development , the principle point to a plane of methods and improve the functionality, optimization simulation results, debug changes, hardware support software, the steps to complete the simulation system of quay cranes research and design development.The Main Solutions of this dissertation are as follow:(1) Designed a functional scheme for quay crane simulator;(2) Designed the method of software integrated, software and hardware integration;(3) Improved the software system functions, optimize the simulation model;(4) Designed and compared several hardware design;(5) Pointed out that the system scalability and future development and design direction.Among them, the use of systems integration and development platform, Virtools simulation optimization is the focus of this article. The key technology optimization simulation model is the vibration of the main simulation, air damping influence and improve the model’s authenticity and real-time. This article vibration is transformed into visual simulation to solve the jitter, respectively, of air resistance, weather conditions and light shade and so on models.更多还原
